Step 1: Materials and Making
-scissors or wire cutters
Get your straw and pipe cleaner and cut the pipe cleaner so that they are the same length. Then just stick it all the way up the straw and bend the straw so it doesn't slip out and there it is, a water filtering straw! Test it out with some dirty water (water with coffee grinds, that is not actually water with dirt) and see how it works.
Keep in mind that this doesn't completely sterilize water and you should use water purifying tablets or boil it as well.
